Lesson details
Lesson outcome
I can take readings from motion graphs to calculate distance, displacement, speed, velocity and acceleration.
Show transcript
Acceleration is equal to the gradient of a velocity-time graph.
A falling line shows decreasing velocity called deceleration, which is a negative acceleration.
Instantaneous speed at a point on a displacement-time graph equals the gradient of a tangent at that point .
The distance travelled is equal to the area under a velocity-time graph.
Displacement is equal to the net positive area under a velocity-time graph.
